This is another problem we faced and had broadcom implement a correction in firmware, so you may want to check for newer firmware for the NIC bit. This case is actually very similar to the panic. The root cause is likely the system powering down without unloading the NIC driver. Just like in a panic, the NIC doesn't realize that the driver went away so it continues operating optimizing for NIC driver being loaded and will mess up when buffers fill. For this problem the fix was simple for them, their firmware in some loop checks to see if it thinks the driver is loaded and if power is on. If the system is off and thinks the driver is loaded, it takes corrective measures (since *obviously* the driver can't be loaded if the system is off). If your vendor doesn't take such a problem seriously, they've got some issues and don't fully get the point of systems management.... ------------------------------------------------------------------------- Take Surveys.
